Capacity & Form Factor

This kit delivers 1.5 TB of DDR5 memory across twelve 128 GB RDIMMs. The 288-pin registered ECC modules run at 6400 MT/s with CL52 latency at 1.1 V, matching the exact rank and timing profile the ASRock Rack GNRAP2D24G-2L+ memory controller expects.

Registered ECC Architecture

Registered buffering reduces electrical load on the controller so all twelve slots operate at rated speed when fully populated. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned downtime in production workloads.

Suited For & Limits

Ideal for administrators scaling the named ASRock Rack platform to maximum supported capacity with validated modules. Not suited for builds requiring UDIMM or SODIMM form factors, consumer desktop boards, or systems that cannot populate twelve registered DIMMs.

Questions about this item

Will the twelve 128 GB RDIMMs need any firmware updates or periodic re-seating to stay stable?

No firmware updates or scheduled re-seating are required; the kit is an exact-match upgrade validated for the ASRock Rack GNRAP2D24G-2L+ and runs at its rated DDR5 6400 CL52 1.1 V settings from first boot.

What limit appears first when all twelve slots run DDR5 6400 continuously at full load?

The registered ECC architecture offloads the memory controller so every slot sustains the rated 6400 MT/s speed and 1.5 TB capacity without down-clocking or population restrictions.

How much heat and power should I budget for a 1.5 TB kit running 24/7 at 1.1 V?

Each module operates at 1.1 V with no heat spreader; total power draw stays within standard DDR5 6400 RDIMM limits and the registered design keeps thermals manageable in properly ventilated server chassis.
